Fallout: London, the long-awaited total conversion mod for Fallout 4 that might as well be a whole new game, is finally out. However, installing it requires quite a few steps, so here is everything you need to do to download, install, and play the Fallout: London mod.

Fallout: London is so big it can be viewed as a standalone title. Image via Team FOLON As things stand, players will only be able to install and play Fallout: London if they own a copy of Fallout 4 on either GOG or Steam. Epic Games owners will have to wait a little longer since the platform doesn’t support rolling back the game’s version. Fallout: London cannot be played on the next-gen version of Fallout 4, and thus cannot work on the Epic Games launcher. Hopefully, the mod’s creators are able to adapt the mod to the latest iteration of Bethesda’s post-apocalyptic RPG so everyone can enjoy it to the fullest.
